Let's divide 231467 by 91
The aim is to understand the frequency of 91 in 231467.

Let's proceed to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 91

Step 2:
The number 91 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 91

On to step 3:
The number 91 fits into 231 2 times, leaving a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 182 away from 231, we end up with 49.
Append the next digit (4) from the dividend to 49 and continue with: 494 / 91

Moving on to step 4:
If we divide 494 by 91, we get 5 and a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 455 away from 494, we end up with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 91

Moving on to step 5:
91 can be fit into 396 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 254.0
Subtract 364 from 396 to get 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 91

On to step 6:
When dividing 327 by 91, we get 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 2543.0
Subtract 273 from 327 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
540 divided by 91 is 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 2543.5
Deduct 455 from 540 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 8:
The number 91 fits into 850 9 times, leaving a remainder of 31.
The next digit of our result is 9. 
Result so far: 2543.59
Subtract 819 from 850 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
The number 91 fits into 310 3 times, leaving a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 2543.593
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
91 goes into 370 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 2543.5934
If we subtract 364 from 370, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
91 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 2543.5934
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
91 can be fit into 600 6 times, resulting in a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 2543.593406
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
When dividing 540 by 91, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 2543.5934065
If we take 455 away from 540, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 14:
850 divided by 91 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 2543.59340659
If we take 819 away from 850, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 2543.59340659 with a balance of 3.1e-08.
